Substitute Part Grouping Explanation

Substitution of the IM02EB5R6K is based on strict electrical and mechanical parameter matching within the allowed tolerances for this product category. The primary substitute identified is the 1025R-38K from API Delevan Inc., which maintains functional equivalence through the following criteria:

Critical Matching Parameters:

• Inductance value: 5.6 µH with ±10% tolerance
• DC Resistance: 1.8Ohm maximum
• Current Rating: minimum 185 mA (substitute rated at 195 mA)
• Q Factor: 50 @ 7.9MHz
• Self Resonant Frequency: 65MHz
• Operating Temperature: -55°C ~ 105°C
• Core Material: Iron
• Shielding: Unshielded
• Mounting: Through Hole Axial
• Physical Dimensions: 0.095" Dia x 0.250" L (2.41mm x 6.35mm)

The 1025R-38K meets or exceeds all specified parameters, with the substitute offering a higher current rating (195 mA vs. 185 mA), providing additional design margin.

Parameter Comparison

Engineering Selection Recommendations

The 1025R-38K from API Delevan Inc. is the direct functional equivalent for the obsolete IM02EB5R6K. Selection of this substitute is supported by:

• Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity.
• Active Product Status: The 1025R-38K is classified as active, providing long-term availability and production support compared to the obsolete IM02EB5R6K.
• Parameter Equivalence: All electrical and mechanical specifications match within specified tolerances, with the substitute offering improved current rating margin (195 mA vs. 185 mA).
• Physical Compatibility: Identical axial through-hole package dimensions ensure direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the 1025R-38K be used as a direct replacement for the IM02EB5R6K without circuit modification?

A: Yes. The 1025R-38K maintains identical inductance value (5.6 µH ±10%), DC resistance (1.8Ohm max), Q factor (50 @ 7.9MHz), and self-resonant frequency (65MHz). Physical dimensions and through-hole axial mounting are identical, enabling direct PCB substitution.

Q: What is the significance of the higher current rating on the 1025R-38K (195 mA vs. 185 mA)?

A: The 1025R-38K provides 10 mA additional current capacity, offering design margin above the original specification. This does not affect compatibility; circuits designed for 185 mA operation remain fully functional with the substitute.

Q: Are there any temperature or frequency performance differences between these parts?

A: No. Both parts operate across the identical temperature range (-55°C ~ 105°C) and maintain the same Q factor and self-resonant frequency specifications at the test frequency of 7.9MHz.

Q: Why is the IM02EB5R6K classified as obsolete?

A: Obsolescence reflects manufacturer discontinuation. The 1025R-38K, classified as active, provides ongoing production availability and technical support for equivalent applications.

Q: Are packaging and compliance certifications identical?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and use identical axial through-hole packaging. No compliance or environmental qualification changes are required for substitution.
